CSX is the product of carbon, sulfur, and the first half of xenon. It comes in a variety of plumages, but it is mostly blue and yellow. The railway is your typical Class I common carrier, though it does have the honour of transporting Tropicana's famous orange juice from Florida to New Jersey by rail.
CSX is the product of HTML and CSS, allowing you to put HTML in your CSS!
